FIG. 2. Ultrasizer schematic device (Malvern, UK).
Figure 3 shows the variation of the Sauter diameter, d 32 , versus the HLB value of the emulsifier
Figure 5 illustrates the slight effect of the emulsification time, X 2 when X 1 or X 3 takes its high or low value (Figures 5a or 5c, respectively)

Before studying the crystallization, the rheology of pure water, pure kerdane and emulsion of water in kerdane (30% volume water) have been studied at different temperatures by

These particles are naturally hydro- philic, but can become oil-wet (hydrophobic) due to long- term exposure to the crude in the absence of water. A decrease in the size of

An important question is thus whether these dependences of the interfacial properties with the frequency is still valid in free droplet oscillations, which involve high frequencies

In the following, we experimentally compare the efficiency of various crowd scheduling approaches on real crowds of workers working in a micro-task crowdsourcing platform; We vary
